Increased drag with wider tires

Mitco39

Shoulda bought a prius if your concerned about fuel economy.

As for strain on the drivetrain, if a boosted Z ain breaking it wider tires wont

What a weak respsonse. As I was merely talking about non stock rubbers. I wasn't complaining about stock mpg now was I?

I was being sarastic as more of a haha sort of thing. Guess I should have added another smiley face. but No sir you were not. You were worried about wider tires hurting your mpg.

However I think going from say a 285 to a 305 in terms of rolling resistance probably works out to about the same drag as adding an aftermarket spointer or spats to the car.

I doubt you would be able to take before and after mpg readings with any sort of reliability.


As far as the power steering, you might notice a bit more resistance, however with my setup I didnt notice much at all personally. If one was worried about it they could add another PS cooler.

I bet if you ran the max values on the tires you would actually increase the economy of the car. Good for mpg, bad for safety and tire wear.

Not sure where you got the idea that I was going to go for wider tires. Just because one posts a question it doesn't necessarily mean one will be doing that.

When my current stock tires go down I may change to 295 at the back.

Either way I appreciate your comments, thank you. ;-)

Sorry if I misunderstood the direction of your thread. I suggest at least taking a look at 305s in the rear. They look good imo.

Just don't camber it out and we can stay friends. haha
